SPELL: A Scalable NLP Method Using Regular Expressions and Large Language Models for Clinical Information Extraction

2025-07-25

Abstract excerpt

<h4>ABSTRACT</h4> <h4>Objective</h4> Electronic health records (EHRs) contain valuable information for clinical research and decision-making. However, leveraging these data remains challenging due to data heterogeneity, inconsistent documentation, missing information, and evolving terminology, especially within unstructured clinical notes. We developed SPELL ( S nippet- P rimed r E gex LL M Pipeline), a scal...
